REGULATING DEVICE FOR FILLING-VALVES.

To a/ZZ whom' t may @o7/warm' "Be it known that I, CHARLES A. CARLSON, a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented certain new and useful Improvements in Regulating Devices for Filling-Valves, of which the following is a speciiication.

. rIhe present invention is intended to be used with filling-valves for liquids of any suitable and well-known construction; and the object of the invention is to provide an automatic regulator for limiting the initial flow of liquid from the valve and producing an even and uniform flow at all times. The regulator is adapted to be inserted into the liquor-duct of any ordinary pressure-equalization valve and when so inserted will greatly facilitate the filling operation.

The invention consists in the features of construction and combination of parts, hereinafter described and claimed.

In the drawings illustrating the invention, Figure l is'a side elevation, partly broken away, of an equalization iilling-valve having the regulator of the present invention inserted thereinto; Fig. 2, a view showing the'casing in section and the movable member unseated;

Fig. 3, a cross-sectional elevation showing the movable member seated; Fig. 4:, a crosssectional elevation taken on linea L of Fig.

3; Fig. 5, a longitudinal sectional view of a pressure-equalization valve of the usual character, havingthe regulator of the present invention attached thereto; and Fig. 6, a top or plan view of the valve-easing, showing in dotted lines 5 5 the line on which the section of Fig. 5 is taken.

As shown, the regulator is applied to an equalization-valve Aof ordinary construction, having a filling-tube o, la sealing-head B, and a screw-threaded neck Z, inserted through the Wall C of a tank and held in place therein'by means of a bushing@ or in any other suitable manner. The neck has therein a liquor-passage D, into which is screw-threaded the regulatorof the present invention and also the usual air-equalization passage D.

The regulator consists of a casing E, open at its lower end, having secured thereto and formed integral therewith a tubular arm e, eX-

ltending down in oblique relation to the body of the casing and provided on its end with screw-threads for insertion into the liquorduct. The casing on its interior is divided into a lower chamber Fand an upper chamber Specieation of rLetters* Patent.

i G, the latter of lesser interior dianlieter than the former and separated therefrom by means i of an annular ange g, Which forms aseat for `the movable member hereinafter described. The tubular arm e communicates with the upper chamber immediately above the annular ange. The upper end of the chamber G is closed by means of a hollow plug H, screwthreaded into the end of the casing and provided with an annular shoulder 7L, adapted to abut against and compress a packing-ring /t for the purpose of forming a tight Joint. AThe plug is bored out 0n its interior to provide a'cylindrieal chamber-I of lesser. diameter than either of the chambers before referred to, and the exterior of the closing-plug is preferably squared, as shown in Fig. 1, to allow said plug to be removed for the purpose ofadjustment or otherwise.

The movable member .I consists of a shank j of lesser diameter than the remainder of the member, which shank is bored out on its interior to provide a passage j', which extends through the shank and intoan enlarged head K, adapted to reciprocate within the plugchamber I as a piston, the head being flattened on the side 70 to leave a slight exterior passage along the interior wall of the closing head.

or plug. The passage j terminates in aventhole 702 of lesser diameter than the passage. `The lower end of the shank terminates 1n an enlarged seating-head L, forming at the point of jointure with the shank a beveled shoulder Z, adapted to seat against the annular ring g, and' the interior of the seating-head is bored out to form a deep recess M, the lower end vof the seating-head being open and adapted to rest against a cross-pin m when dropped or in normal position.

In use the liquor in the tank will entirely surround lthe regulator, and when the filling- `valve is initially opened and before perfect equalization takes place the head of the liquor in the tank will cause the liquor to rush rapidly into the regulator prior to its flow through the lvalve, and said inrush of liquor, owing to the bell shape of the seating-head', will throw up the movable member of the regulator against its seat, thereby preventing the iow of liquor around the movablel member and causing the liquor to flow through the passages in the shank and pistou-head, which are made small to limit the ioW of liquor, thereby limiting tlie initial iiow of kliquor which will enter the chamber in the closing-cap and gradually force down the piston-head until the seat is broken, allowing the movable member to fall b v gravity when perfect equalization has taken place and the liquor to flow directly through the tubular arm and into the valve. The direct flow will not take place until the pressure in the bottle and in the tank has been perfectly equalized, so that when the liquor finally begins to iiow suflicient time will have elapsed for the equalization of the pressure in the tank and in the bottle. The regulator, in other words, serves as a check to prevent the too rapid initial flow of the liquor; but said iiow is never entirely cut off, but is momentarily arrested by the device of the present invention. In order that the liquor which enters the chamber above the piston-head may flow back into the casing of the regulator, it is desirable to Hatten one side of the piston-head, as best shown in Fig. 4, to provide an escape-passage for said liquor, as otherwise when liquor had-once entered the chamber in the closing-cap it would form a permanent cushion therein and prevent the future operation of the device.

The chamber G has a less diameter than the chamber F for the reason that the shank J is of less diameter than the seating-head L, which arrangement leaves a substantially uniform annular space around the shank and head, so that the flow of liquor from one chamber to the other will not be interrupted. rJhe passage j is preferably of greater diameter than the outlet-port if in order that the liquor may have an easy flow, but a restricted discharge which would not be the case if the entire passage were of the small diameter of the discharge-port.

It will be seen from the foregoing description that the device is simple in construction and applicable for use with all styles of filling-valves into which it may be inserted or from which it may be removed, without in any way changing the character of the valve.

What I regard as new, anddesire to secure by Letters Patent, is-- 1. In a regulator for use with filling-valves, a casing adapted to be connected with the liquor-passage of a fillingvalve, an annular shoulder within the casing, a closed head for the casing, a movable member within the casing provided with an enlarged lower end adapted to seat against the annular shoulder, an enlarged upper end slidably held within the closed head, and a shank of lesser diameter between the enlarged heads and further provided with a passage through the shank opening above the annular shoulder for allowing the passage of liquor when the regulator is seated, substantially as described.

2. In a regulator for use with filling-valves, the combination of a casing, a tubular connection for the casing, an annular shoulder within the casing, a closing-head, a movable member provided with a shank, an enlarged bellshaped head at the lower end of the shank adapted to seat against the annular shoulder, a piston-head at the upper end of the shank and slidably held within the closing-head, a passage leading through the shank and pistonhead and opening on the interior of the closing-head for providing an indirect passage through the movable member when the same is seated, substantially as described.

3. In a regulator for use with filling-valves, the combination of a casing, a tubular connection for the casing, an annular shoulder within the casing, a closing-head, a movable member provided with a shank, an enlarged bellshaped head at the lower end of the shank adapted to seat against the annular shoulder, a piston-head at the upper end of the shank and slidably held within the closing-head, a passage leading through the shank and pistonhead and opening on the interior of the closing-head for providing an indirect passage through the movable member when the same is seated, and an abutment for limiting the return movement of the movable member, substantially as described.

4. In a device for regulating the iiow of liquids, the combination of a casing provided with an outlet-port, an annular shoulder located below the outlet-port, a closing-head of lesser diameter than the easing and secured thereto, a movable member consisting of a shank having at its lower end an enlarged, hollow'bell-shaped head and adapted to seat against the annular shoulder, and at its upper end an enlarged piston-head adapted to reciprocate within the closing-head and having a passage leading from the interior of the bellshaped head and opening into the closinghead for providing an indirect passage for the flow of liquor when the movable member is seated, substantially as described.

5. In a regulator for use with filling-valves, the combination of a casing, a tubular arm screw-threaded at its outer end and diagonally7 extending from the casing for insertion into the liquid-passage of a filling-valve, an annular shoulder in the easing located below the tubular arm, a closing-head screw-th readed into the upper end of the casing, a movable member within the casing consisting of a shank having at its lower end an enlarged, hollow bellshaped head adapted to seat against the annular shoulder and having at its upper end a piston-head iiattened at one side and adapted to reciprocate within the closing-head and having on its interior a passage leading from the interior of the bellshaped head through the piston -head and opening into the closing-head for providing an indirect passage for liquid when the movable member is seated, substantially as described.
